The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this 16-day window for Kennebunk Beach is a tough one. The honest truth is, there isn’t a single surfable option in the whole stretch. The data shows poor surf conditions across the board, so we’re looking at a blank run that goes all the way from now, Tuesday, August 4th, through to Wednesday, August 19th.
Wave energy is incredibly weak throughout, with the highest combined energy hitting just 99 (moderate) on Tuesday afternoon, but that’s paired with a messy onshore wind. Most days barely scratch into double digits for energy, and the swell height never gets above 3 ft. The swell is coming from the SSE, which is a sheltered direction for this spot, and the period is short, mostly between 3 and 10 seconds, meaning weak, mushy, and disorganized waves.
The only silver lining here is the water temp. On Tuesday morning, the water is sitting at 65°, which is exactly average for this time of year in Maine. No anomaly to speak of, just standard cool summer water.
For a couple of mornings, like Friday August 7th and Sunday August 9th, you get glassy conditions with zero wind, but the swell is practically non-existent at 0.7 ft and 1 ft respectively. Then, way out at the end of the run, on Tuesday August 18th and Wednesday August 19th, we finally see some clean offshore wind from the ENE and NE, at 12-15 mph. But the swell is still tiny, at 1 ft to 1 ft, with low energy (25-28). It’s a tease.
For Kennebunk Beach, this kind of flat, poor run is more normal for the area. Don’t lose hope – forecasts can change, but for now, this stretch is a write-off. The board stays in the car.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
